On QUERY2 IOCTL don't query counts of correctable
and uncorrectable errors, since when RAS is
enabled and supported on Vega20 server boards,
this takes insurmountably long time, in O(n^3),
which slows the system down to the point of it
being unusable when we have GUI up.

Please completely drop the code. We usually don't keep commented out
code in the driver.
1. Alex suggested this when we chatted--this is why it is commented.
Sounds like a misunderstanding to me, usually it is Alex who insists on
dropping the code.
2. He suggested the same thing last night and 2.5 hours before your email,
I posted a patch in which the code is commented out--did you not see it?
It's threaded, it appears above, 2.5 hours before your email.
Sorry for the redundancy, didn't had seen that in my inbox yet when I
wrote the reply.
Regards,
Christian.
Regards,
Luben
